A major objective for modern research in heterogeneous catalysis is developing materials integrating distinct active sites that are capable of efficiently catalyzing different types of elementary reaction steps within an overall cycle. For example, reactions of oxygenated derived from biomass, of many post-consumer plastics, and of CO<sub>2</sub> often rely on efficient dissociation of molecular hydrogen (for which Pt group metals are effective catalysts) and C-O bond activation (which often involves sites capable of acid-base catalysis). Proximity between the different types of active sites is important, but it is often challenging to develop multifunctional catalysts that have truly independent sites, i.e. the presence of one material at the surface influences the properties of the other. This presentation will describe several approaches for preparing bifunctional materials for C-O bond activation reactions, typically via combination of a Pt group metal with organic or inorganic materials capable of acid-base chemistry. Acid or base functionality can be introduced to supported metal nanoparticles via deposition of oxophilic metals or organic acids/bases with tunable properties. However, the adjacency of these sites can strongly influence properties such as site accessibility, geometry, and electronic structure. This presentation will focus on the importance of these interactions in driving selective catalysis, including possibilities where beneficial synergistic effects can be realized.
